All products by EPCOS AG are basically designed to conform to the German VDE regulations
and/or EN standards. The respective regulations or standards are given for each component type.
Many of our components have also been approval-tested in accordance with national and interna-
tional regulations. The approval marks and quality assurance marks are listed in the data sheets.
Examples of approval marks:
Example of a quality assurance mark:
In future, chokes will be tested in accordance with the new European standard EN 138 100. A uni-
form European mark of conformity has not yet been defined. For the time being the national marks
of conformity are used (e.g. VDE) and the corresponding European standards is stated beside the
mark.

When selecting EMC components – in particular in case of power line applications – the safety reg-
ulations applicable to the relevant equipment must be observed.

General Technical Information
VDE
Ensure a proper electrically conductive connection between the filter case and/or filter ground
and the metallic case of the interference source or disturbed equipment, and
provide sufficient RF decoupling between the lines at the filter input (line causing the interfer-
ence) and the filter output (filtered line), if necessary by using shielding partitions.
